I have a pet theory that certain high spatial frequencies bleed into being perceived a colors anyway. The reason being that the red, green, and blue cones in the retina each have a different amount of space between them but are otherwise organized in the same pattern. Thus if the brain sees something with the same spacing as the blue cones, its going to assume that's caused by it being a blue object (rather than a black/white object which happened to have the same spatial freq as the blue cells). You seem to know the literature here, is there anything validating or invalidating my pet theory?

- hunter2_ 4y agoI'm no expert, but that sounds a lot like how halftone and dithering work.
